LMV7235M7/NOPB

Overview

The LMV7235M7/NOPB is a single-channel, ultra-low power, low voltage comparator manufactured by Texas Instruments. It features rail-to-rail input capability and an open-drain/push-pull output configuration. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical specifications include a maximum propagation delay of 62 ns, a maximum input offset voltage of 6 mV at 5 V, and a typical common-mode rejection ratio (CMRR) of 67 dB with a power supply rejection ratio (PSRR) of 85 dB. It draws a maximum static current of 95 µA and has a maximum input bias current of 0.4 µA at 5 V. The component is housed in a compact SC-70-5 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated applications
• Rail-to-rail input stage allows operation near supply rails
• Flexible output configuration with open-drain or push-pull options
• Compact SC-70-5 surface-mount package design

Applications

• Portable consumer electronics requiring low power dissipation
• Battery-powered measurement instruments
• Threshold detection circuits in low-voltage systems
• Signal conditioning for microcontroller interfaces

Procurement Notes

Verify the specific suffix M7 against the official Texas Instruments datasheet to confirm the SC-70-5 package variant and tape-and-reel packaging details. Ensure compatibility with the required operating temperature range and supply voltage constraints before integration. Cross-reference the part number with authorized distributors to confirm availability and authenticity, as variations may exist between manufacturing lots or regional specifications.

Selection Notes

Select this component when designing circuits that demand minimal quiescent current alongside fast response times in low-voltage environments. The rail-to-rail input feature simplifies interface design with sensors or logic outputs that swing close to ground or the positive supply. Consider the open-drain output option if level shifting or wired-OR logic connections are necessary within the system architecture.

Part Context

This device belongs to the LMV723x family of comparators from Texas Instruments, which are engineered for high performance in portable and space-constrained applications. The family includes variants with different channel counts and package types, such as the dual LMV7234 and quad LMV7236 models. These components share similar electrical characteristics, focusing on low power, wide bandwidth, and rail-to-rail operation to support modern low-voltage digital and analog systems.

Replacement Considerations

Direct substitutes within the same family include the LMV7235M7X/NOPB, which shares identical electrical specifications but may differ in reel quantity or minor packaging tolerances. Other compatible alternatives in the series include the LMV7239M7/NOPB for higher speed requirements or the LMV7234M5/NOPB for dual-channel needs. Always verify pinout compatibility and thermal performance when substituting.
